To a whom, it may concern:

Be it known that I, STEPHEN H. GARsT, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Heating Apparatus; and Ido declare the following to be a full,- clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements instoves, ranges,&c., and pos sesses the structural features hereinafter described andclaimed.

The object of the invention is to provide a stove or range for domesticuses which possesses a high degree of efliciency and utility, combinedwith simplicity, all as will be here inafter more fully described.

y. In a detail description of my invention ref erence is made to theaccompanying drawings, of which Figure 1 is a top plan view with partsbroken away. Fig. 2 isa top plan view of the plate, showing a slightmodification consisting of a flat surface. Fig. 3 is a detailperspective view of one of the detachable extension-segments. Fig. 4 isa sectional view on the line :20 w of Fig. 1. Fig. 5 is a sectional viewon the line as a: of Fig. 2. Fig. 6 is a detached view of a radial armwhich may be utilized by applying a number of such arms in place of thesegments shown in Fig. 8.

In a detail description of the invention similar reference charactersindicate corresponding parts.

Referring to Figs. 1 and 5, 1 designates a plate havingadownwardly-turned annular flange 2, which forms a surrounding wall thatincloses the lower interior of the stove or heater and prevents anyescape of the accumulated heat therein through any portion of said wall.Owing to the effects of unequal expansion and contraction of the surfaceof the plate 1 and the annular flange 2, I pro-- vide said plate in theform of a series of concentric corrugations 7 and a series of radialslots 8, which absorb or compensate any unequal expansion in theplate 1. To the same end I divide the plate 1 in any number of segments,as in Fig. 2 and Fig. 4. These are held together by bolts 9 and 10. Thespace between the segments serves to counteract the unequal expansionand contraction. The downturned annular wall 2 is imperforate, and thesame extends from an annular rim 5, which is dropped below the surfaceof the plate 1 and forms a marginal flange around the rim of said plate.contains a multiplicity of orifices 6. Through these marginal orificesin the stove or heater the accumulated heat on the interior of the stoveor heater can only escape, the annular wall 2 confining, as beforestated, the heat below the stove or heater. When the hot air on theinterior of the heater moves from the center toward the circumference ofthe heater, it comes in contact with the solid flange or wall 2, and isthus deflected upwardly to the orifices 6. The solid wall or flange alsoprotects the accumulated heat within the heater from side drafts of air,the tendency of which would be to drive an excess of the heat to one orthe other side of the heater, and would thus create a further tendencyto cause unequal expansion and contraction.

The under side of the plate 1 is thickly studded throughout with amultiplicity of long depending pins or projections 3, which lie in thepaths of the products of combustion. By thus coming in contact with theheat on the interior of the device the said heat is absorbed or storedtherein to an extent proportionate to the amount of absorbing-surfacepresented by this multiplicity of ins. In thus absorbing andaccumulating the heat within the device it is greatly in tensified andheld so that the temperature within the heater may be maintained afterit has reached a given point by the use of comparatively little fuel.The utility of the heater is materially extended, so that a greaternumber of vessels or articles may be placed upon the plate or in closeproximity thereto. For this purpose I provide a multiplicity ofextension-segments 1, which may be assembled around the plate 1, andthus made to increase the effective area or diameter of the plate. (SeeFigs. 1 and 3.) Any number of these segments may of course be employedfrom one to the number required to complete the circle. In the drawingsI have shown four as being necessary to complete the circle. As asubstitute for these extension-segments one or more radial arms 11 maybe employed around the rim of the stove or heater orplate. The imierends This marginal flange 5 a 12 of these arms project into the orifices6 at the points where said arms are placed. The lugs 14, extendingfromthe sides of said arms, come in contact with the projections 7 on thedropped rim 5 of the heater, and thus said arms are prevented fromdrawing away from the heater or plate. The projections 7 eX tend aroundthe extreme margin of the late and are instrumental in supporting in aevel manner any vessel that may be placed on the plate with or withoutthe extension-segments or arms.

It will be seen that when any vessel or artiole is resting upon theheater-plate and the extension-segments 4 or arms 11 a portion of suchvessel resting upon the plate will receive heat through the pins orprojections 3, from which said heat is transmitted in great volume tothe plate, and the portion of such vessel resting on theextension-segments or arms will receive heat directly from the flamesissuing through the orifices 6.

I claim as my invention 1. In a heat-accumulator for fire apparatus, asupport, a ridge disposed around the edge of said support and having aseries of orifices therein, and an extension-ring consisting of amultiplicit of segments adapted to be placed around said support.

2. In a heating apparatus, a heater having its margin dropped below theplane of the upper surface of the heater,- and an annular downturnedflange extending from the outer circumference of said dropped margin andforming an inclosing wall around the heater, the dropped margin of saidheater having a multiplicity of orifices therein, and a series ofextension devices attachable to said dropped margin and by means ofwhich the effective area of the heater may be increased at any point,such increased area receiving heat through the orifices in the droppedmargin, substantially as specified.

3. In a heating apparatus, a heater having its interior surface thicklystudded with a multiplicity of depending heat-absorbing projections, theouter margin of said heater terminating in a dropped flange which liesbelow the plane of the upper surface of the heater, said dropped flangehaving extended from it an annular downturned flange which provides aninclosing wall for the heater, said dropped flange having amultiplicityof orifices, and a series of extension devices at tachable to saiddropped flange and supportable upon the annular wall, and by means ofwhich the effective area of the heater may be increased, substantiallyas specified.

In testimony whereof I affix my signature in presence of two witnesses.
